Sorry mate, all 3.x compilers are way past end-of-life now; there will never be
another release.
Your best bet is to hand-edit the header files in your local install. I don't
remember the exact recipe, but of the two places where this bug crops up, one
can be worked around by adding "__attribute__ ((__unused__))" to the relevant
variable declaration, and the other one has to be fixed by adding
"__attribute__ ((__noinline__))" to the function declaration.
I haven't tested these workaround for performance impact. Shouldn't be too bad
if you're not calling the functions from the middle of a loop that runs
millions of times.

okay, but I wish that you wouldn't freeze 3.x when 4.x is still in Alpha. If I
could upgrade to a stable 4.x for the change... I would.

Alpha?!? What do you mean, exactly? Certainly we have a very stable 4.3.x
release series, and previously we had 4.2.x, and previously 4.1.x...

My understanding was that 4.x was not available. I'll have to re-check. sorry
for the noise.

Subject: Re: Spurious 'might be used uninitialized'
warnings in STL headers with -O2
You are confusing the state of the Cygwin port of gcc with gcc in
general.

Possibly, but I cannot find the download for 4.x.x.
Why does it have to be so confusing ?
http://sourceforge.net/project/showfiles.php?group_id=2435
This is the location that I got ALPHA from.
It appears that the best 4.x.x download is: Testing:
gcc-4.3.0-20080502-mingw32-alpha
I see no other reasonable downloads.

Confirmed that this happens with 3.4 for the i686-pc-cygwin target, though not
for the i686-pc-linux-gnu target. It is fixed in current mainline for both targets.
